Abstract (en)

Multiple packet traffic profiling models are created from known packet traffic flows that are labeled, where a label is an actual value of a factor influencing one or more characteristics of the known packet traffic flow. Features, which are different from the factors, are measured for each flow. Flow clusters are defined from the labeled traffic flows by processing their features and labels. The profiling models are created based on cluster information. When an unknown packet flow is received, the multiple packet traffic profiling models are evaluated according to a confidence and a completeness associated with each of the packet traffic profiling models. The packet traffic profiling model with a predetermined confidence and completeness is selected and applied to profile the unknown packet traffic flow.
